When first install Dexpot (1.6 beta ) I have no problem checked on Dexcube, but after i go through all the setting play with them my Dexcube not working the "checked" missing and I can't select it and check again.

Found the probable cause! Apparently Dexcube has problems with directory junctions.

My %ProgramFiles% folder as usual is “C:\Program Files (x86)” which is ridiculously long and has spaces in it. That’s why I also have a junction called “C:\bin32” (created with mklink /j) that points to “C:\Program Files (x86)”. Dexpot is installed in %ProgramFiles%\Dexpot.

When I start Dexpot via “C:\bin32\Dexpot\Dexpot.exe” the problem with Dexcube happens.
